algoart

Algorithmic Art is a creative blend of programming, design, and the arts.

analysis-of-buzz-in-twitter

A R-code to find temporal correlations among various features to predict the activity in Twitter.

dynamic-time-warping

A MATLAB function to align two temporal sequences (ideally 3D accelerometer values) and compute the Dynamic Time Warping(DTW) distance. The alignment is for correcting the phase difference between the temporal sequences.

MATLAB code

extraction-of-approximate-gait-cycles-from-noisy-gait-data

A MATLAB Code to extract gait cycles, even when the data is very noisy and there is no periodicity in the gait cycles

facial-emotion-recognition

: Recognition of facial expressions from gray scale images using Convolutional Neural Networks.

fourier-affine-transform

gait-cycle-extraction

A MATLAB to extract gait cycles using wavelet decomposition technique. The algorithm uses

online-character-recognition

A MATLAB GUI where the algorithm uses direction and slope to detect numbers in real time. This can easily extended to characters as well. You will need to input the number using the GUI.

optimal-threshold-selection

R-code to choose the optimal threshold using the ROC, sensitivity, specificity and accuracy curves. The function in R

random-forest-boosting-trees

An R-code implementation

systolic-peak-detection-in-arterial-blood-pressure-waveforms

A MATLAB code which uses gaussian filtering and peak identification algorithms to identify the systolic peaks in ABP waveforms. Please refer to

teager-energy

A MATLAB Code to compute teager energy of 3D accelerometer data.

tracking-the-motion-of-larvae

A MATLAB code to track the head and tail motion of a larvae in a video.
